How it sells itself

Drop Engine runs limited launches end to end. Pick a product and a go-live time and it stays hidden as a draft until the moment you choose. A storefront widget collects notify-me signups while shoppers wait, with an optional countdown. At go-live the product publishes itself and every subscriber gets an email with a link to buy.

Schedule a flash sale or deal on any product, variant, collection, tag or your whole store. Set a percentage or fixed discount, pick start and end times, and it runs itself. Countdown timers and a countdown bar show the deal on home and product pages. A dedicated Deals page, built for you, lists every live deal. Low stock and units left badges add urgency and FOMO.

Key points
  • Schedule a drop: product stays a draft until your exact go-live time
  • Waitlist widget on the product page captures emails before launch
  • Automatic launch email to every subscriber the moment the drop goes live
  • Schedule flash sales that start and end automatically — no manual toggling.
  • Live countdown timers on home, product & All Deals pages create urgency.
  • Discounts apply automatically at checkout — shoppers need no coupon codes.
  • Match your brand with 10 widget themes & color controls — no coding needed.
